RECORDING APPARATUS.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed November 15. 1904. Serial No. 232,802.

To all whom "it may concern;

Be it known that I, I'IARRY l3. PALMER, a citizen of the United States, residing in the borough of Manhattan, city of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Recording Apparatus, of which the following is a specification, reference being bad therein to the accompanying drawings, forming a part thereof.

Broadly my invention relates to recording apparatus generally including time-controlled recording apparatus, and in various of its specific embodiments, and in all of the specific embodiments illustrated in the drawings accompanying this specification, my invention relates to time-controlled employees time-recording apparatus for recording the time at which the various employces of a factory or other like institution arrive at or depart from their place of work, orfor recording the time at which the various employees commence or complete a given job or portion of their days work.

My invention may be embodied in divers forms'of employees time-recording apparatus, and in various of its specific embodiments, and in all its specific embodiments illustrated in the accompanying drawings, my invention is embodied in employees time-recording apparatus for the so-called individual card system in which a separate card is assigned to'eachemployee and is used .as a record medium upon which the time-recording apparatus may print or make a record of the time of that employee. Such individual card systems are sometimes known as unlimited time-recording systems, since the number of employees whose time may he recorded therebyis practically unlimited, in con tradistinction to the limited time-recording systems in which the time of all the employees is kept upon a single card or record medium so that there is necessarily a limit to the number of employees whose time can be recorded by the apparatus.

In various of its embodiments my invention relates to distributed time-recording systems which employ a number of separate time-recording mechanisms or appaiatuses located at different points throughout a factory or like institution and commonly controlled, for instance through a controlling electric circuit, by a common master chronometer or time controller. Such distributed time-recording systems are particularly useful in what is known as the cost system in which the workmen are required to record the time of commencing and the time of completing the various separate jobs or pieces of work to which they are assigned during the day, in order to determine the cost of the labor involved in such separate jobs. system it is practically essential that various recording apparatuses should be located in the various rooms or work shops throughout the factory in order to be readily accessible to the workmen in sucli rooms as their jobs are commenced and completed.

In such a cost The objects of my invention, broadly stated, are'simplicity and reliability of operation, simplicity and economy of construction, and economy of maintenance.

Another object is to make the recording operation'entirely automatic so that the workman or employee isrequired'merely to place his card or record medium into the recording mechanism or apparatus in order to make the desired record upon the card.

My invention has many objects which might be stated in more specific terms as subservient to the broad and general objects above mentioned, forinstance 'it is one object of my invention to maintain the recording mechanism or record marking mechanism of the'timecontrolled recording apparatus normally in slow gun, that is to say, so that its record markers or recording de vices proper do not move continuously or periodically under influence of the controlling chronom'eter, but are normally stationary and therefore only consume power when they are moved in the operation of marking a record upon the record medium or card.

Another object of my invention is to make'ther'ecord markers or recording devices proper separately and independently operatable or movable so that in the event of injury to one of the" record markers or its operative mechanism the operation of the other record markers will not be affected.

Divers other objects subservient to the broad purposes of my invention might be enumerated at this point, but can be most readily brought 0ut,-howe'ver, in' the course of the more detailed specification which 'follows and which describes particularly those specific embodiments of my broad invention which havebeen illustrated in the accompanying drawings.

In the accompanying drawings-Figure lis a front elevation of a time-recording apparatus embodying my invention and adapted to be controlled either separately or as a sub-apparatus together with similar time-recording apparatuses in a distributed time recording system, by a master chronorneter which is not shown in this figure. Fig. 2 is adiagmm of electrical circuits illustrating the manner in which the master chronometer or time controller 160 controlsa re'co'r'iiing apparatus such as that shown in Fig. land select ively determines the particular record markers or re cording devices proper which shall be operated at any given instant to mark a record upon the'card or record medium.

This figure illustrates a construction wherein hand power of the operator is employed 'to actuate the type bars, in lieu of electric power employed in the constructions of the foregoing figures. The view point in Fig. 19 is from the right of Fig. 20 and the section of Fig. 19 is taken on the central plane indicated by the line 19 of Fig. 20. Fig. 19" is a front detail elevation of the manually operated handle 134" of the mechanism shown in Figs. 19 and 20. The view point of Fig. 19* is from the left of Fig. 19. Fig. 20 is a front elevational view of the modified construction shown in Fig. 19, the view point in Fig. 20 being from the left of Fig. 19, all but two of the type bars or record markers being shown in their horizontal or non-operating positions and sectioned on the plane indicated by line 20 of Fig. 19. Fig. 21 diagrammatically illustrates a modification in the calendar mechanism or card positioning mechanism which locates the card, when it is placed in the hopper of the recording mechanism, in position to receive its record mark in or upon the proper day column of the 'card, as determined by the day (day of the week) upon which or during which the record is made. Fig. 22 diagrammatically illustrates a modification in the card-controlled circuit-closing switch for throwing into circuit the magnets which control and actuate the record marking mechanism. larly well adapted for cooperation with the recording mechanism shown in Figs. 17 and 18. Fig. 23 diagrammatically illustrates adistributedemployees timerecording system in which a-numbcr of sub-recorders or sub-recording apparatuses are electrically con trolled by a common master chronometer.

The recording mechanism proper, or that portion of the time-recording apparatus which actually prints the time record on the time card, is contained within the lower box or casing-332 of the recording apparatus illustrated by the external view of Fig. 1. This casing comprises a suitable base board such as 142, a vertical back board 141 secured to the back; edge of the'base board, vertical side boards 143 and 144 mounted upon the right and left edges of the base board, a vertical lower front board 138 mounted upon the front edge of the base board,- a rearwardly slanting upper front board 139 extending upward from the upper edge of the lower front board, and a horizontal top board 140 secured upon the upper edges of the back board and Fig. 19 is a central sectional side elevation of Fig. 17 is M This modification is particu- 110.

side boards and the upper or slanting front board. A vertical main frame plate 115 is mountedwithin the casing as a. partition extending across the casing from one side board to the other and from the base board to the top board. Along the lower and vertical sides of the main frame plate its inner surface abuts against and is firmly secured to shoulders formed respectively upon the base board and upon the vertical side boards. The main frame plate extends upwardly to and engages with the under side of the top board 140 except at the middle portion on the upper edge of the frame plate where it is provided with a slot 293 which acts as a guide for the shiftable card hopper 77.

The hand shaft or hopper-shifting shaft 101 projects forwardly through the vertical or lower front board 138 of the casing of the recording mechanism, and

thence extends rearwardly into the casing and through the journal 169' of the shaft bracket 169, and thence through the main frame plate 115 at a point \vhcre'tbo plate is provided with a journal boss 166, which may be formed integrally, as shown, upon the rear side of the plate. The inner or rear end of the hand shaft extends some distance beyond, or in rear of, the rear end of the journal boss 166 and projects through an arc shaped slot 92 formed in the hopper-shifting rock arm 92, which at its lower end is provided with a suitable hub pivotally mounted upon a stud 93 inserted into a suitableb'oss formed upon the rear side of the main frame plate 115 at a point underneath the journal boss or hand shaft bearing 166. The hand shaft carries a pinion 165 located between the hopper-shifting rock arm 92 and the journal boss 166.- This pinion is rigidly fixed to the shaft and meshes with an internally toothed arc rack 92 fixed upon the front face of the hoppershifting rock arm 92 and-disposed about the pivotal stnd93 of the rock shaft as a center. The are shaped slot 92 is also disposed about such pivotal stud as a center, the purpose of the slot being to permit rocking movement of the rock arm 92 withoutinterference from the hand shaft 101. A positioning or locking ratchet or cam 102 is secured upon the rear end'of the hand shaft 101 by means of a set screw 102 which passes through the hub 1.02 of the locking ratchet and engages the hand shaft. A locking lever 95 is pivotally mounted upon a stud 94 inserted into the rear side of the main frame plate at a point to one side oi'the hopper-shifting rock arm 92. From this pivotal stud the locking lever 95 extends laterally underneath the hand shaft 101 and between the hopper-shifting rock arm and the lower edge of the locking ratchet 102. A locking roller 99 is mounted upon a spindle stud 1.00 inserted in the rear face of the locking lever 95 at a point underneath the locking ratchet 102. The free or swinging end of the locking lever 95 extends some distance beyond the locking ratchet 102 and is connected to the lower end of a tension spring 97 extending upward and at its upper end anchored to asuitable spring stud 98 inserted in the rear side of the frame plate 115 at a point above the swinging end of the locking 19-1 91; The tension 9? tends force the locking lever upward so as to maintain its locking roller 99 in engagement with the periphery of the locking ratchet 102, and the periphery of this locking ratchet is provided with a number of locking notches or serrations 102", into which the locking roller enters as the locking cam is rotated. When the locking ratchet 102 has been rotated so as to bring the locking roller 99 into locking position in one of the locking notches 102", the locking ratchet will be retained or locked in such locking position and its hand shaft 101. will thereby be prevented from any further angular movement until it is forcibly impelled by the hand crank 131 so as to forcibly raise the locking roller out of engagement with the locking notch.

The hand crank 134 is provided with a suitable hub .35 secured by means of a cotter pin 136 and locking screw 1.37 upon the front or outer end of the hand shaft 101 where the shaft projects through the front board 1?8 oflhe casing. Upon the lower or swinging end of the hand crank 134 is formed a forwardly projecting spring barrel 132 bored from its roar end with a bore of sullicicnt diameter to receive a compression spring 131, which is interposed between the bottom of the spring bore at the forward end of the spring barrel and a suitable spring collar 129 formed upon the rear or inner end of the plunger stem 1.30 around which the spring is coiled. The spring collar tits and is guided by the rear end of the spring bore. The outer or forward end of the plunger stem 130 passes through a guiding bore in the outer or forward end of the spring barrel and of smaller diameter than the spring bore, and such forward end of the plunger stem is inserted in and secured to the handle 133. A rounded teat or locking projection .128 extends from the rear end of the spring collar 129 toward the front board 138 of the casing and is normally inserted into one of the locking holes 122", 123, 124", 12 .126 or 127", which are bored into the face of the front board 138 and respectively surrounded by metallic escutcheons 122, 123, 124, 125, 126 and 127. These escutcheons bear suitable inscriptions such as those illustrated in Fig. 1 and corresponding to-certain columns upon the record medium or time card, and each designating the beginning or the ending of a certain period of occupation, the beginning and ending of which it is desired to. record upon the time card interms of hours and minutes. The pressure of the compression spring 131 upon the spring collar 1.29 normally thrusts the plunger stem and its locking teat or projection rearward toward the front plate and thus maintains the locking teat in its locking engagement with either one of the locking holes in which it has been placed, and in such locking position of the plunger stem its handle 133 is held against the.forward or outer end of the spring barrel 1.32 and acts as a. stop to limit the rearward thrust of the spring upon the plunger stem.

When it is desired to operate the hand shaft, the handle is drawn forward by the operator, thus compressing the locking compression spring 131 and withdrawing the locking teat 128 of the plunger stem from the locking hole in which it has been inserted, and the hand crank 134 may then be rotated so as to impart rotation to the hand shaft 101. The hand shaft is fixed in longitudinal position by means of a collar 19] secured with a cotter pin upon the hand shaft; and abutting the oat-er or forwar-t-i end of the Nam {warns 1:??9 sc; prevent. longitudinal movement of the hand shaft in rearward d ircctiou," and by means of the abutment of the hand shaft pinion 165 against the rearmost end ofthe journal boss 166 which prevents longitudinal moveintent of the hand shaft in forward direction. The

hand shaft pinion 165 and the locking ratchet 102 are I pend from their points of support in substantial paralboth securely fixed upon. the inner end of the hand shaft and rotate with the hand shaft, and each position of the hand crank 1.34 which enables it to be locked by one of the locking holes passing through one of the escutchmn plates on the front of the casing, also brings the locking ranlust 102 into position to be locked by the locking roller 99.

The rotation of the hand shaft pinion 165 causes the hopper-shifting rock arm 92 to swing about its pivotal center 93 in one direction or the other according to the direction in which the hand shaft is rotated. The rock arm 92 at its uppermost end terminates just underneath the top board 1 of the casing, and this upper or swinging endof the rock arm is provided with a suitable boss or lug 92 having a slot 92 disposed longitiulinally with respect to the rock arm. A hopper stud 25H passes through this slot and is inserted into the back end of a boss 77 formed upon the rear side of the card hopper 77. The head of the hopper stud 294 overlaps the slot in the rock arm and bears upon the rear side of the slotted end of the rock arm so as to retain it firmly in position.

The card hopper consists of a hopper proper 77 projecting from the inside of the casing upward through a slot; 140 in the top board 140 of the casing and having its portion which rises above the surface of the top board provided with flaring sides so as to facilitate the introducti'on of a record card. The lower edge of the rear side ofthe hopper rests upon and is guided by the bottom of the hopper-guiding slot 293 in the top edge of the main frame plate, and the stud boss 77"is formed on such rear side of the card hopper just above the guiding edge of the slot. The lower edge of the front side of the card hopper proper'77 is forwardly and laterally extended into a-horizontal guiding rib 77", which rests upon and is guided by the upper edge of a horizontal guide bar 204 screwed at its ends upon the front side of the main frame plate 115. The rear side of the guide bar 204 is cutaway between its ends, which are screwed to the frame plate so as to provide a guiding space for receiving the guide webs 7 7 of the hopper which are inte'grally and dependingly formed upon and at opposite ends of the horizontal guide'rib 77*. Upon each of the guiding webs 77 and just underneath the horizontal guide bar 204. is integrally formed a lower guiding rib 77 projecting forwardly under the horizontal guide bar so as to engage its lower edge. Thus the upper hori zontal guiding rib 77 and the guiding web 77 and the lower guiding ribs 7 7" together form the sides of a channel in which the horizontal guide bar 204 is embedded. The lower guiding webs 77, provided with rectangular apertures to reduce their weight, are formed integrally depending from the lower edges of the lower guiding ribs 77, and the lower edges of these lower guiding webs 77 are guided by means of a suitable lower guide bar 78 mounted on the front side of the main frame plate 115 and underneath the ends of the hand shaft bracket 169, and secured by means of the bracket studs 170 and their clamping nuts 17], which serve to fasten pair of left and right flat card-guiding springs 172 and 173 are mounted upon the front sides of the lower guiding ribs 77 and at the inner ends of such lower guiding ribs, that is to say, at their ends nearer the vertical cen ter line of the hopper. These card-guiding springs delelism with,- and near to, the front side or surface of the main frame plate 1.15 and are also parallel with and disposed just within the inner vertical edges of the lower guiding webs 77. When the time card 179 is inserted into the card hopper 77, as illustrated in Figs. 9 and 10, it passes down between the lower guiding webs 77' and also between the card guiding springs and the front face of the frame plate 115, and the card guiding springs hold the card securely in position and flatly against the fro it surface of the frame plate. As the hand crank B4 is shifted from one position to another, the consequent rotation of the hand shaft 101 and its hopper-shifting pinion 1.65 meshing with the arc rack 92 on the hoppershifting rock arm 92, causes such rock arm to swing from one position to another so that its upper slotted end impels the hopper shifting stud 294 and causes the card hopper to slide laterally from one position to another along i ts horizontal guide bars 204 and 78 and along the front face of the frame plate 115 against which it is held by such guide bars, and thus is determined the lateral position of the time card as it is placed into the card hopper to receive a record.

The calendar-controlled card-positioning levers or day levers M", Tu", W, Th, F and So, which operate to determine the printing position of the card on Monday, Tuesday, Wednesday, Thursday, Friday and Saturday, respectively, are horizon fully and pivotally mounted' on the rear face of the frame plate. These day lovers are mounted in two sets of three each, one set ineluding the levers M, W. and F and the other set including the lovers Tu, Th" and 811. The levers of the first set are disposed on the right (looking toward the machine from in front) thereof of the vertical center plane of the latitude of transverse movement of the card hopper, and are mounted in a common pivot lug 276 seecured to the rear side of the frame plate. The levers of the other set are similarly mounted .upon the left side of the center plane of lateral movement of the card hopper and are likewise mounted in a common pivot lug 276 secured to the rear side of the frame plate. The sides of the common pivot lugs 276 and 276, which abut against the rear face of the frame plate, are provided with slots such as 277 (Fig: 16) to receive the day levers, which are of flatform, and common pivot pins 278 and 278, respectively, pass through the common pivot lugs and through the pivotal centers of their respective day levers. gored and their inner or adjacent ends interlapat the center plane of lateral movement of the card hopper. The set including the levers, M W and F is higher than the opposite set of day levers so that the lever M is first in successive order of the levers from the upper one to the lower one, such successive order being the order of the days of the week commencing with Monday and to which the day levers correspond or during which they are operative to position the time card in receiving its record.

The inner overlapping ends of the day levers are provided with forwardly extending card'engaging tongues such as M" which project through individual'holes in the frame plats and extend a short distance beyond or in front of the front surface of such plate so as to 'in-. tersect the vertical plane or path of movement in which the time card is inserted into the card hopper. Flat The opposing sets of day levers are stagcard-engaging and switch-operating springs M Tu etc., which may be designated as day springs, are mounted upon the day levers near their inner ends and have forwardly extending tongues such as M corresponding in form to the card-engaging tongues of the day levers themselves, and pass through the'same frame holes as the card-engaging tongues of the day levers upon which the springs are respectively mounted. The card-engaging tongues upon the day springs are narrower than the card-engaging tongues upon their respective day levers, and the card-engaging tongues upon the lovers are provided with channels such as M' into which the card-engaging tongues of the day springs may be depressed so that the tongues of the springs and levers may be flush upon their upper surfaces when the springs are pressed down by the time card as it is inserted in the hopper to receive a record A vertically sliding card operated switch which controls the actuative electric circuits of the recording mechanism, is mounted upon the rear face of the frame plate 115 just behind the interlapping ends of the day levers. This sliding switch is provided at its upper end with two vertical guiding pins 80 which are inserted into the upper end of the main bar 80 of the switch and which slide vertically in guide holes in the rearwardly projecting horizontal leg or extension of the upper L-shaped guide bracket 79 screwed upon the rear face of the frame plate. The lower guiding pin 80 is likewise secured to the lower extremity of the vertical main bar 80 and is guided in a suitable guide hole in the rearwardly projecting horizontal leg of another L-shaped guide bracket 81- similar to the guide bracket 79 and similarly mounted upon the frame plate. A retractive compression spring 80 is coiled upon the lower guiding pin 80 and interposed between the horizontal leg of the'lower guide bracket 81 and the lower end of the main bar 80 of the switch.

This retractivo spring 80 tends always to return the main switch bar, and all the parts carried thereby, to their uppermost positions which are determined by the abutment of the upper end of the main bar 80 against the horizontal leg of the guide bracket 79 acting as a stop. The main bar 80 of the card operated switch carries a contact blade 80 which, when the main bar slides downward, engages and makes rubhing conductive contact with a contact spring 84 vertically mounted upon a suitable bracket 82 which straddles the main bar 80 and which. is secured upon, but insulated from, the rear face of the frame plate. Inserted into the front face of the main bar 80 of the card operated switch and arranged in vertical order and projecting forwardly from the main bar, are a number ofswitch actuative pins 80 80', 80 SO 80 80 and 80 When the card actuated switch is in its normal or uppermost position where it is stopped by the upper guide bracket 79, each of these switch actuative pins lies just above the inner end of one of the day levers and just underneath the free or movable end of the day spring of that particular day lever, so

that,-as the movable end of the day spring is carried downward by the downward pressure of a time card upon the upper side of its cardengaging tongue, the movable end of the day spring engages the switch actuative pin and presses the pin and the card actuated switch downward, compressing the rctraetive compression spring 80 and causing the contact blade 80* to make contact with its cooperating contact spring 84. The rear edges oi the inner ends, or the interlapping ends, of the day lovers are provided with pinclcaring slots such as M (Fig. 16) in order to'permit the switch actuative pins to move freely downward through such pin clearing slots and without interference from the day levers Of course, as soon as'the downward pressure upon one of the switch actuative pins is relieved, the retractive compression spring'S O returns the card operated switch to its normal position and breaks contact between the contact blade and its cooperating contact spring 84.

Upon the outer ends of the day levers, that is to say, upon their swinging cnds outside their axes and-0pposed to their interlapping ends, are mounted magnetic armatures M", Tu", W", Th", F, and Sa*, named in the order of their respective day lovers from top to bottom. A number of act-native day magnets M,'Tu, W, Th, F and Sa, cooperate with these magnetic arm'atures. These day magnets are mounted upon the'fro'fit face of the main frame plate 115 and are divided into two sets, corresponding to the sets into which their -day lovers are divided, one set of magnets being disposed on either side of the middle of the'frame plate. The polar ends of the magnet cores pass through the frame plate, which is made of non-magnetic material to avoid magnetic short-eircuiting of the fiux'fr'oin the magnets, and at their inner ends the poles of the mags nets are presented to their respective armatures 'Inounted upon the day levers. When any one of these day magnets is energized, its armature will be drawn for ward toward the poles of the magnet and the day lever, which carries the armature and corresponds to the particular day magnet which is energized, will be swung about its pivotal axis so as to move its inner or interlapping end rearwardly and partially withdraw its card-engaging tongue from the aperture in which '11; projects through the frame plate. 'Of course the-cardengaging tongue of the day spring is'sirnultaneously Hi5 withdrawn together withithe card-engaging tongue (if the day lever upon which the day spring is mounted, and this retractive movement of the day lever and its day spring is sufficient in extent to completely withdraw their card-ongaging tongues from their positions in which they intersect the plane of, or'path of movement of, the time card as it inserted into the card hopper; so that after such retractive'movement or withdrawal of the card-engaging tongues of the day lever and its day spring, the time card as it is inserted into the card hopper will pass in front of the ttmguesandwithout engaging them or being stopped by them. Each day lever is retained in either of its two extreme positions, that is to say, in either its card-engaging position or its card-clearing position, by means'o f an L-shaped detent spring 282, one leg of which is'secured by a screw to the rear side of the frame plate and'the other leg of which projects horizontally rearward and at its and engages with lateral pressure a small V-shaped extension formed upon the outer swinging end of the day lever and projecting just slightly beyond its magnetic armature. When the day lever is in one of its extreme positions, the detent spring presses on one side of the V-shaped extension and when the lever is in the opposite position the detent spring presses on 1 30 the other side of the V'shaped extension, and in either case it requires some effort to force the V-shapcd cxtension against the lateral pressure of the detent spring so that the detent spring shall pass from one side of the extension to the other, and byv opposing such resistance to either movement of the day lever, the detunt spring tends to hold it in either one of its extreme positions until it isforcibly moved to the other extreme position.

Should all the card-engaging tongues of the day levers and their day springs be withdrawn from cardengag'ing positions, the card, when inserted by lllu operator into the card hoppcr, would then be pushed down in front of and beyond the card-cngaging tongues of all the day levers and their springs, and the lower edge of the card would ultimately come into contact.

with the card-engaging tongue of an extra card-engaging spring or day spring Su mounted directly upon the rear face of the frame plate 115 at a point In the right of the center of the mechanism and extending horizontally leftward toward the center of tho nn-t-hanism, its card-engaging tongue being similar to the card-engaging tongues of the other day springs and likewise projecting from the free or movable end of.

288 has its parallel arms disposed in lu'irizoutal planes and pivotally mounted on the ends of the pivot lug 276of the left hand sct of day levers, and upon flu: ends of the common pivot pin 278 of such set of day levers. From their pivotal mountings the horizontal .arms of the U-shaped replacing bridge extend rightward to a point near the vertical longitudinal center plane of the mechanism where such horizontal arms are joined by the cross bar or bridge proper which is disposed vertically just behind the inter-lapping ends of the day levers so that the vertical cross bar forms a sort of bridge extending over the movable inter-lapping ends of both sets of day levers so as to engage such inter-lapping ends of the daylevers and force all of them, together with their day springs or card-engaging springs, forward into card-engaging positions, when the replacing bridge is swung forwardly about its pivotal axis.'.Such forward swinging movement. of the replacing bridge is effected by means of a ri'eplacing lever 289 located just below the lower horizontal arm of the replacing bridge and swinging in a horizontal plane about its pivotal mounting in the pivot lug 291 secured to the rear face of the frame plate at a point on the left side of the mechanism. The extreme right. or swinging end of the replacing lever 289 is bunt. into an upwardly extending finger 289*iwhich projects buhind the lower horizontal arm of the U-shapi-d .rcplacer and engages such arm to push the replacing bridg forward when the replacing lever is swung forward about its pivotal center by the attraction of a magnetic armature 290, secured upon the replacing lover, toward i s magnet 811. secured upon the front side of the frame plate just underneath the left hand sclot' the day" lever actuative magnets. The polar ends of the con-s of this day-lever replacing magnet Sn project through the frame plate 115 and are presented toward the armature 290 of the replacing lcvcr.

The left hand set of actuative day magnets, together with the replacing magnet Su, have a common magnetic back iron 206, while a common magnetic back iron 205 is likewise provided for the right hand set of day magnets.

The type bars or recording devices proper, such as 12, (Fig. 9) are pivotally mounted upon independent pivot pins such as 181 and within independent type bar brackets such as 180 secured upon the front face of the frame plate 115 and underneath the card hopper. The type bars are divided into two sets of twelve each, one set on either side of the vertical longitudinal center plane of the mechanism, one of the sets for printing the hours and the other set for printing the five-minute intervals of the hour. The hour set of type bars is disposed on the right and the minute set on the left. Each type-bar bracket consists in a plate 180 of the outline clcarly-imlicated in Fig. 9 and provided with a central slot parallel to the plane of the plate which receives the flat pivotal cud of the type bar and prevents its torsional displacement so as to maintain the type bar in its proper plane of pivotal movement. The type-barbrackets and pivotal pins of each set of type bars are arranged in circumferential'order about, or with respect to, a common striking or printing center or axis, and the common printing centers of the hour and minute sets of type-bar brackets and type' bars, are located side by side just above the tier of inter lapping ends of the day levers, the common printing center of the hour set being on the right and that of the minute set on the left. The type bars lie normally in substantially horizontal positions. At their outer ends they are formed into rounded heads upon which are mounted the types proper or record markersvproper such as 183. These types proper are provided with stems, such as 184, which are inserted through the.

heads of the type bars and upon which are screwed fastening nuts such as-185 which rigidly secure the types upon the ends of their respectivetype bans. All the type bars of either the minute'or hour set swing upwardly about their pivotal centers so as to bring their types proper into common printing. positions which are located at the common centers about which their respective sets of pivotal brackets are disposed in successive order in the arcs of circles.- The lower edges of the type bars have curvilinear gouges 190 near their pivotal ends, and these gauges form cam surfaccs 189. The type bars are actuated by magnetically operated type-bar actuators qr actuating levers, such as 12 and ()0 of the hour and minute set respectively, which are formed of flat stock and at their lower ends pivotally mounted on suitable pivot pins 202 and in suitable pivot lugs such as 201. Each set of type-bar actuators has its pivot lugs arranged in a staggered series disposed in or along concentric arcs d cscribcd about the common striking or printing center of its corresponding set of type bars. The upper. or cam-engaging ends 188 of the actuators enter the slots in the type-bar brackets and normally project upward into the curvilinear gouges 190 and engage the cam surfaces 189 thereof, while the type-bars normally rest upon such cam-engaging ends of the type ban actuators as stops which limit the downward or retractive movements of the type bars. The type bars are normally held in such normal or retracted positions, and after being actuated are returned to such normal positions by means of type-bar rctraetive springs such as 182, having one end inserted for anchorage in the front face of the frame plate at a point below the pivotal center of the type bar and having the other end or movable end hooked to pass over the upper edge of the type bar and press the type bar down into its normal position.

Upon the rear edge of each type-bar actuator and near its lower or pivoted end is mounted an armature such as 199, and each actuator armature cooperates with a type-actuator electro-inagnet such as 12 (Fig. 9) mounted upon the rear side of the main frame plate with the polar ends of its cores projecting forwardly through the frame plate and presented toward the armature. The actuator armaturcs are staggered in correspondence with the staggered relation of the pivot lugs of their respective type-bar actuating levers while the actuator magnets are also staggered in correspondence to the staggered arrangement of the armatures. In order to attain compactness of assemblage of the actuator magnets they are constructed in a special form having unusually small lateral dimensions. Each: magnet comprises three parallelmagnetic bars or cores disposed in the plane of movement ofits type-bar-actuator and projecting from a common narrow. back ironsuch as 193 forwardly through the main frame plate upon which the magnets are mounted. The single coil such as 12 of each magnetds mounted u'ponits central b'ar 198as a core, while the outer mag netic bars 192 lie close to the periphery of the coil.

The'back irons-of the staggered sets of type-actuator magnets inter-lap at their adjacent ends and upon the interlapping-ends of the back irons of-either set of typeactuator magnets is mounted an arc-shaped insulating plate such-as 197, and upon the upper side of the rear facesof these insulating plates ismounted a single arc-shaped:conductive bus-barv 196wl1ich is co-extens-ive withthearcs-of both the insulating plates. Upon the lower sides ofthe rear surfaces of the insulating plates-are mounted a number of'insulated binding screws 195, one foreach type-actuator magnet, while each type-actuator magnet also has a corresponding binding: screwsuch as 194 mounted beside its corresponding insulated binding screw, but inserted-in the commonbus-bar 196 in lieu of the insulating plate. Each of the type-actuator magnets has its opposing terminals connected to its corresponding binding screws inserted in one of the insulating. plates or in the common: bus-bar, andseparate lead wires such as 12% (Fig-9) are connected to the insulated bindingscrews of the individualactuator magnets and are thus connected with the corresponding terminals of the magnets, while the opposing terminals of all the magnets are connected to the common bus-bar 196 through their corresponding bus-bar binding screws. An extra binding screw 374, inserted in the rear face of the common bus-bar at its medial point between the two insulating plat-es, sew-es as fer lea-d wires 371 and 371 leading respectively to the ribbon feed-magnets 207.and-207", as will hereinafter be more fully described.

When'any' one of the type-actuator magnets is encrgized, its magnetic attraction draws its corresponding actuator armature rearwardly toward the magnet, thus swinging its corresponding type-bar actuating lever, rearwardly toward the main frame plate 115 and loreing the upper or cam-engaging end 188 of the actuator rearwardly against the cam surface 189 of its corresponding type bar and toward the pivotal center 1.81 thereof. The resulting pressure of the cam-engaging end of the actuator upon the cam surface of the type bar forces the type bar to swing upwardly about its pivotal center and thus carry its type proper or record marker proper 183 into striking or printing position at the common striking or printing center of the set of type lHll'S to which it belongs. When thus actuated the type proper strikes upon the front-face of a record ribbon 178, which is held in front of the card hopper in a manner which will be more fullydescribed hereinafter. The type strikes the ribbon at the common printing or striking center of the set to which the type belongs and, providing the record card is in position in the card hopper behind the ribbon presses the ribbon forcibly forward against the card and imprints a record. Although the impulse with which the type bar is actuated by its actuating lever is sufficient to carry its type with forcible impact against the ribbon, the cam surface of the type bar is so formed as to per-' mit it to rebound immediately and carry its type proper out of engagement with the ribbonor at least out of striking position in which the type presses theribbon against the card, and such recoil of the type bar is assisted by its retractive spring 182. When the type-actuator magnet is again deenergized the force of the type-bar retractive spring 182 is sufficient to swing the type bar back to its normal position whileits cam surface simultaneously forces its corresponding actuating lever also back to normal position, which is determined by a stop screw such as 187 against which the actuating lever strikes upon its return stroke and which is inserted'in the hand-shaft bracket 169: A separate stop screw 187 is of course provided 'for each 105' type-bar actuating lever, the two stop screws nearest the middle of the shaft bracket being mounted in its depending medial lug, the lower end of which. is mounted upon the medial shaft-bracket stud-167 projecting from the front face of the frame plate, while theother stop screws are inserted in lateral arc-shaped extensions of the shaft bracket which are providedfor the purpose and which at their outer ends are mounted upon the shaft-bracket studs 170 also projecting from the front face of the frame plate and, as already noted, serving the additional purpose of securing the' lower card-hopper guide-bar 78 to the frame plate.

The record ribbon or printing ribbon-178 is stretched, and is fed, horizontally just in front of the lower guiding webs 77 of the card hopper and just in front of the cardreceiving space between such guide webs, and hence just in front of the time card when the latter is in its record-receiving position in the card hopper. At its. right and left ends the ribbon is wound upon suitable 125 spools er behhins 2-25 221i respectively. The right ribbon spool 226 is fixedly mounted upon a spindle 253. A feed ratchet 227 is also fixedly mounted upon the spindle just below the ribbon spool and the spindle is journaled just belowthe feed ratchet 130
